  Downstream testing recently discovered that inbound
connections can't
 be migrated properly, because the new socket gets an address conflict
 with its corresponding listening socket.  It turns out this can be
 avoided by delaying bind() until after we're already in repair mode.
 
 Patch 4/4 is the actual fix here.  Patch 3/4 adds a test program
 checking the behaviour to doc/platform-requirements.  Patches 1 & 2
 fix minor problems I spotted in doc/platform-requirements writing 3/4.
 Only 4/4 will need to be backported.
